Embodiment Construction

[0013]Referring now to the drawings and specifically to FIG. 1, agricultural tillage implement 10 is towable by a tractor (not shown) or other vehicle and is shown with main tillage implement 15 and soil finishing system 20 that improves soil leveling, as explained in greater detail elsewhere herein. Main tillage implement 15 is shown here as a cultivator with main implement frame 25 that has multiple sections, represented as main frame section 30 and outer wing sections 35 on opposite sides of main frame section 30. Main implement frame 25 supports a set of ground-engaging tillage tools 40 for tilling soil during a tilling session for seedbed preparation. Tillage tools 40 are shown here as sweeps 45 mounted to shanks 50 that are attached to main implement frame 25. Although shown as sweeps 45 mounted to shanks 50, it is understood that ground-engaging tillage tools 40 may be other ground-engaging tillage tools, such as coulters, disks, and rippers.

[0014]Still referring to FIG. 1, f...

Abstract

An agricultural tillage implement is provided with a soil finishing system that includes a multi-bar harrow and a down pressure-controlled finishing tool that are arranged with respect to each other to enhance soil tilth and leveling, including reducing residual shank grooves in tilled soil, to improve seed bed preparation.

Description

FIELD OF THE INVENTION[0001]The invention relates generally to tillage implements and, in particular, to an agricultural tillage implement with a soil finishing system having a multiple bar harrow and hydraulic down pressure for a finishing tool.BACKGROUND OF THE INVENTION[0002]Tillage implements such as cultivators are getting larger and more complex over time to improve tilling efficiency and seedbed characteristics. For example. cultivators are getting wider to allow tilling more soil in a single pass, which improves equipment productivity. Shanks and other components of the cultivators are also getting larger and more robust to allow increased travel speeds while tilling, which further improves equipment productivity. Further efforts have been made to improve soil leveling and other seedbed characteristics, such as by incorporating soil finishing systems which may include secondary harrows and / or formed bar baskets behind main tillage tools of the tillage implements. However, fi...
